Abstract
The existence of antiferromagnetism in rare-earth superconductors exhibits varieties of new physical phenomena. Experiments have highlighted the magnetic specific heat anomalies in antiferromagnetic superconductor. Structured around a Ginzburg-Landau theory, this article presents the role of magnetic field on the specific heat near the antiferromagnetic superconductor phase to normal state phase transition in rare-earth superconductors. The magnetic specific heat is calculated both at the antiferromagnetic superconductor phase and normal state. The qualitative agreement between theory and experiment is discussed.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
